How we work
We are a mobile locksmith. We come to you.
The call
A call comes in after a key twists hard in a storefront deadbolt, a master key stops turning in a commercial cylinder, or exit hardware feels loose at the latch. In Thornbury Township, that usually starts with someone already trying the key again, checking another copy, or working the lever more than once. We listen for the lock type, the way it is behaving, and whether the problem stays with one key or moves with the hardware. That tells us what we need to look at first.
What we check first
Before we touch anything, we check the door alignment, the cylinder face, the condition of the keyway opening, and how the latch or exit device sits against the opening. A bored cylindrical lock behaves differently from a rim lock or a mortise lock, and the master key setup changes the order of the check. In Thornbury Township, that first look decides whether we are dealing with a worn cylinder, a set screw issue, or hardware that needs adjustment at the opening.
The work itself
At the door, we open the lock and work on the part that is binding, not on the whole assembly at once. On commercial locks, that can mean removing a cylinder, setting a new cylinder in place, correcting a master key setup, or resetting exit hardware so the lever, trim, and latch parts move together. We work at the lock itself on the business premises, including in nearby Coatesville when the same hardware needs the same kind of attention. The metal parts stay the focus.
What changes afterwards
When the work is finished, the new cylinder is the part that changes, or the existing cylinder is the part that has been adjusted, and that is what changes how the key enters and turns. On a master key system, the change is in the way the keying is set inside the cylinder, while the lock body and exit hardware keep their place on the door. In Thornbury Township, that leaves the hardware set up around the lock, the key, and the latch parts rather than around a temporary fix.

Commercial Locksmith, in short
Locks, cylinders, master keys and exit hardware on business premises.
Worth knowing
A rim lock changes the work because the cylinder, latch, and interior housing are all set on the surface of the door. We remove the inside trim, free the cylinder from the mounting hardware, and check the tailpiece or cam that drives the latch. If the cylinder is the part worn out, we swap that piece and keep the body in place. If the latch is the problem, we strip the case, inspect the spring and bolt travel, then reset the parts so the lock opens cleanly at the door edge.
A mortise lock is handled differently because the case sits inside a pocket in the door and the trim only shows part of the mechanism. We pull the inside and outside trim, then work on the lock body itself instead of just the cylinder. If the cylinder threads into the case, we unscrew it and match the tailpiece length to the lock body. If the latch, deadbolt, or spindle is binding, we open the case, clean out worn parts, and fit the cylinder and trim back to the mortise lock in Thornbury Township.
A bored cylindrical lock has its own set of parts, so the work stays focused on the knob or lever chassis, the latch tube, and the cylinder hub. We check whether the door has a separate deadbolt above it, because that changes which parts we service and which parts stay alone. If the key cylinder is removable, we replace just that section and leave the chassis and latch in place. If the latch assembly is worn, we pull the roses, remove the through-bolts, and reset the cylindrical body, spindle, and strike hardware at the door.
Jobs we have done
Questions
I lost the master key for our Thornbury Township office door and need the rest of the suite kept separate.
We can open the lock, change the cylinder if needed, and set up a new master key arrangement for the doors that need to work together. We check which doors should share access and which should stay separate, then we fit the hardware and cut the keys to match.
After the rear exit bar on our warehouse door started sticking, should I stop using that door?
Yes, we should look at it before you keep using that exit hardware. A sticking bar can come from wear, loose parts, or a cylinder that is binding. We inspect the hardware, open the lock if needed, and replace the parts that are causing the problem.
My front office key turns hard in the cylinder, but only on the conference room door.
We can open the lock, inspect the cylinder, and replace it if the key wear or the cylinder wear is causing the bind. If the key is still usable, we can also cut a fresh one from it so the door does not keep fighting the same worn edge.
Why are you checking my side office lock with the old key after it’s open?
We want to see how the cylinder responds before we leave it in place or change it. A key that drags, sticks, or turns unevenly can point to wear inside the lock, not just on the key. That check helps us decide whether the cylinder needs repair or replacement, and whether the latch is lining up with the door.
Why do you need my master key after opening the rear exit hardware?
We use it to compare the master key setup with the lock that was giving you trouble. That lets us see whether the issue is in one cylinder, in several keyed alike locks, or in the way the exit hardware is working at the opening. It gives us a clear starting point before we adjust the lock or change the cylinder.
